lMPROVEMENT IN WHIFFLETREE S.

Specification forming part of Letters Patent No. 163,455, dated May 18,1875; application filed March 17, 1875.

To all whom it may concern Be it known that I, THOMAS CARROLL, ofPrairie City, in the county of McDonough and in the State of Illinois,have invented certain new and useful Improvements in Whiftletrees; anddo hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in a check-wheel attached to awhiffletree on a pole'or tongue, as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichrepresents a perspective view of my invention.

A represents the tongue or pole, and B the whiftletree, pivoted theretoby the bolt to. O is the hammer-strap, connecting the tongue with thebolt a, in the usual manner. D represents a half circle or wheel,provided with shoulders b I), at equal distances from the center of theback part. This wheel is fastened to the rear or to theunder side of thewhiffletree B, in the center, and extends back of the hammer-strap O toa slot, 93, formed in the same. The shoulders I), striking the sides ofthe slot, keep the whiffletree from striking the wheels of the vehicle.This wheel also supports the center bolt a, and strengthens thewhiffletTee.

It will be seen that with my invention the bolt 60 passes through thewhiffletree and tongue, for connecting the same in the usual manner, andthat the wheel D, by means of the stops d d, can only turn a limiteddistance in either direction. This wheel, as Well as the hammer strapdescribed, can be employed with any running-gear of a vehicle in use.

By taking out the bolt a the whiffletree can be moved rearward, andbecome quickly detached from the tongue.

I do not claim a whifflet-ree provided with a curved bar attached to therear, as I am aware that such is not new.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The wheel D, attached to the whiffletree B,

and provided with shoulders I) b, in combina. tion with the hammer-strapG, having slot 1',
